Hi Everyone,
I have a J35a4 with J32a2 heads, cam and intake... brand new short block and rebuilt heads... engine does an amazing job and is very dependable. Tim Beadle out of phoneix built this for me. I have about 6 runs on the car so far over the past couple of seasons.
I am looking to:
1) have a dependable engine
2) gain approximately another 80-100 whp by adding a turbo
3) stay on pump gas 93/91 octane
4) copy your setup if you have done this successfully
One tuner said it is doable as long as I keep the boost under 8 lbs.
I am wondering if the stock rods/pistons can dependably hold up.
I have several friends who have done this with a stock motor (not an a4/a2 combo) and have dependable engines--but they all run 50/50 or 100 percent 110 octane.
My main concern
1) I don't want to grenade my engine as I run it pretty hard in the dunes for 30-60 min runs.
The a4/a2 combo has an increased compression over the stock a4. Stock a4 is 10:1. I am not sure exactly what it is, but my guess is around 11:1
Questions:
1) Has anyone else out there added a turbo to a bone stock honda with this setup and run it on pump gas 93/91?
2) Has anyone lowered the compression on an a4/a2 combo and added a turbo and are running on pump gas 93/91?
Overall, I am hoping to find someone who has successfully done this. If so, I would love to copy your setup.
If not, then my guess is I will need to upgrade my piston and rods to reliably handle the increased compression to run on pump gas.
Your advise is appreciated--Thank you!!
